Augrented Insights Report for 423 11th Street

423 11th Street is a three-story, three-unit Old Law Tenement building located in Brooklyn's South Slope neighborhood, built in 1901 and currently owned by Philip Guliara Jr. The property has experienced several significant compliance issues in recent years, particularly in 2024 and 2025, with multiple violations related to unauthorized construction work.

Between May 2024 and April 2025, there were at least six documented complaints regarding work without proper permits in the occupied multiple dwelling, some of which resulted in enforcement actions including a penalty of $1,280 issued by the Environmental Control Board for unauthorized work near the staircase area. Most notably, there were two instances of work being conducted contrary to a Stop Work Order, with one violation issued in January 2025 being particularly concerning.

The building also has recurring issues with compliance requirements related to pest management, having received four consecutive Housing Maintenance Code violations from 2021 to 2024 regarding the failure to file annual bedbug reports as required by HPD regulations. While there was one documented plumbing issue in 2019 regarding water supply problems, which was resolved within two days, the more pressing current concerns relate to the recent unauthorized construction activities and the outstanding bedbug reporting violations. An inspection in April 2025 related to Special Operations Compliance yielded a violation, though specific details were not provided in the records.
